VEHICLE WHEEL RIM.

' Application filed July 29,

.To all whom it may concern.'

Be it known that I, WiLLiAM N. BOOTH, a citizen of the United States of America, residing at Detroit. in the county of lVayne and Btate of Michigan, have invented certain new and useful Improvements in Vehicle IVheel Rims, of which the following is a. specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle wheel rims of the demountable type, in which the rim is transversely split to permit collapsing for engagement of the tire. It is the object of the invention to provide means for lool;- ing the abutting end portions of the SplitA rim'so as to prevent separation of the same, and to this end the invention comprises the construction as hereinafter set forth.

In the drawings:

Figure 1 is a perspective view of a portion of a vehicle wheel and demountable Tlm' Figure 2 is a cross section thereof; and

Figure 3 is a perspective view of the clamping plate.

A is the felly of the wheel and B thefelly rim having a flaring fla nge C on its inner edge forming a seat for the d emountablg rim D, which is transversely split at E. F are clamping lugs for engaging the outer edge of the demountable rim and holding the same to its seat.

It is usual to provide the lugs F with wedge portions (l which enter the space between the felly band B and demountable rim D, and duringv the tightening of the clamps wedge said demountable rim outward. This wedging action causes a tension upon the demoun-table rim, tending to separate the end portions thereof upon opposite sides of the split, and to prevent suoli a result I have provided the following construction:

The rim D is provided on its opposite sides with tire-retaining flanges D and D2 which preferably terminate in beads D3 formed by returnbending the metal. In these beads and upon opposite sides of the split E in the rim are formed recesses and H adapted to be engaged by projections I and I on a connecting tie member. This tie member I preferably form as an integral part of one of the clamping lugs, which lug is positioned tO embrace the split in the rim. The locking device just described is 4.applied to the outer edge of the tire rim, but it may Specification of Letters Patent.

also be advantageously applied lto the inner edge thereof. In the latter case the tie meinber J is not a wedge,^as the rim is seated upon the flange C, but the member J may be secured by the saine clamping bolt which secures the wedge lug on the opposite side Of the rim. Thus. as shown in Figure 2. the member J is fashioned to pass around and beneath' the flange C and to engage the clamping bolt K adjacent to the head thereof, while the opposite end of said clamping bolt engages the wedge clamping bolt F.

However', this construction is not essential, for it is obvious that a locking member may be applied to one edge ofthe demouiitable rim, other means being provided for locking the Opposite edge. x

As shown, the connecting tie member L is provided with the groove L for engafrino the bead D3, and theclamping lug of which the tie member is an integral part, is provided with tlie inwardly extending projection M lengaging the lower edge of the ilange of the felly band B extending radially inward at the side of the felly A. The clamping lug also having the wedge portion G, the lug is securely held from radial movement either outwardly .or inwardly relative to the felly so that the member L with its groove maintains the demountable rim D in accurate radial position. The projections I and I closing the ends of the groove in tie member reinforce the latter.

From the above description it is seen -that the clamping lug of which the tie member is an integral part positions the rim both radiallyand periplierally and the projections upon the tie member maintain'the ends of the Split rim adjacent to each other and reinforce the tie member.

What I claim as my invention is:

j l. The combination with a transverselysplit demountable rim provided with a tireretaining flange at one side thereof, said flange having a beaded outer edge, of a A felly-band, a tie-plate clamped to said fellyband, arranged to embrace the split and to extend adjacent to said tire-retaining flange of the rim, said beaded outer edge of the rim and said tie-plate having cooperating wedging recesses and projections, and a bearing for said rim at the side of said folly-band opposite said tire-retaining flange.

2. The combination with a transverselysplit demountable rim having tire-retaining flanges upon opposite sides thereof, said flanges having wedge-shaped notches therein near the split, of a felly-band providing a seat for the inner side of said i'iin, a wedge clamping plate for engaging the outer side of said rim to hold the saine upon its seat, said plate embracing the split in the rim and having projections for engaging said wedge-shaped recesses in the outer .tireretaining flange, a tie-plate embracing the split in the rim and having projections for engaging said wedge-shaped recesses in the inner tire-retaining flange, and a clamping bolt passing through the felly-b'and for engaging saidtie-plate and wedge clamping plate to retain the same in engagement with the rim.

3. The combination with a wheel telly and a transversely-split deinountable riin, of clamping plates vprovided with means for accurately spacing said riin relative to said felly, one of said plates provided with sec ond means for holding the ends of said riin adjacent to each other.

4. The combination with a wheel felly and a transversely-split demountable rim having a tire-retaining flange at one side thereof, said flange having a beaded outer edge with notches therein adjacent to the split, of

clamping plates provided with grooves for engaging said beaded edge` one of said clamping plates provided with projections for engaging the notches in said edge, and means providing a beaiing for said riin at the side opposite said tire-retaining flange.

5. The combination with a wheel felly and a transversely-split deinountable rini having a tire-retaining flange at one side thereof,

ifiosgsi.

said flange having a beaded outer edge with notches therein adjacent to the split, of a clamping plate provided with a groove for engaging said beaded edge and with projections closing said groove and engaging the notches in said beaded edge, and a beaiiiig for said rim at the side opposite said tireietaining flange.

(i. The combination of' a ti'aiisve1'sel vsplit denionntable i'iin haviiw a tire-retaining flange at one side thereof, said flange having a notched beaded outer edge, the notches being on opposite sides of' the split and adjacent thereto, for the purpose described.

T. The combination of a clamping plate having a grooved portion on its inner or rim-engaging face and projections closing said groove, for the purpose described.

8. The combination of a transveisely-split deinountable rini having a bearing for a riin at one side and a tire-retaining flange at the opposite side thereof', said flange havinga beaded outer edge provided with wedge-shaped notches therein on opposite sides of' the split and adjacent thereto, for the purpose described.

9. The combination of a clamping plate having a grooved portion on its inner face near the outer end and wedge-shaped projections closing the groove, for the purpose described.

In testimony whereof I affix my signature, in the presence of two witnesses.
